, who considered it as antero-ventral marginal denticles interconnected by a calcitic layer, i.e., a frill. This structure appears to be hollow in the isolated LV (Fig. 8A, B), but it is impossible to confirm whether a radial pore canal is present. A tiny opening seems to be present at the extremity of the nose in the LV of the carapace, but the definition of the scan does not allow further precision. In both LV, the postero-ventral margin is thickened and bears three parallel rows of full spines that are more strongly developed in the largest LV; they also develop anteriorly and are interrupted by the oral concavity (

. As mentioned above, the RV is posteriorly nested into LV. The contact develops into a sort of contact groove (Fig. 8H, I) that progressively reduces and flattens until the anterior end of the posterior subventral node, where the ventral contact consists of RV being overlapped by LV (Fig. 8H, J). An anterior contact groove progressively redevelops around mid-part of the median subventral node until the anterior end of the anterior subventral node (Fig. 8H, K).

Auxiliary (bairdoppilate?) teeth and sockets are poorly developed on the carapace, possibly being less expressed in juveniles, but they are visible anteriorly on the isolated LV, more clearly on individual scans than on reconstruction (Fig. 8A, C).

specimens are intramural. Further analysis of juvenile specimens will be of importance to compare the ontogeny of pore systems with the ontogenetic history of calcification. The study of complete carapaces will clarify how pore canals are organized in the two valves of these highly asymmetrical ostracods, if the asymmetry of the valves also corresponds to an asymmetry of the pore systems.

The 3D tomography reveals that these nodules are actually hollow and penetrated by tiny pore canals that can only be fully studied with higher resolution scans (Fig. 8H, I). They can easily be recognized in several of the published specimens, for instance in

They cannot be tracked along their entire length through the valve thickness because of their small diameter that is close to the resolution limit of the CT-scan. However, their position perpendicular to the valve margin and their regularly spaced disposition reminds radial pore canals.
